Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 4 generators on 24 points:

(1,2)(3,7)(4,5)(6,8)(9,10,13,15)(11,14,12,16)(18,21)(22,24);(2,5)(6,7)(9,11,13,12)(10,14,15,16)(18,22)(20,23)(21,24);(9,12,13,11)(10,14,15,16)(17,18,19,21)(20,24,23,22);(1,3,4,8)(2,6,5,7)
